### Please describe the problem.

With the latest git-annex-standalone version `git annex assist` and `git annex sync --content` print uninformational messages of the form "remote.<name\>.url" to stderr. This doesn't really break anything, but it makes annextimelog print a warning because of the non-empty stderr.


### What steps will reproduce the problem?

Run `git annex assist` or `git annex sync --content`.

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Yes! I am now using git-annex through annextimelog to track my working times and automatically submit them to my employer and it is working really well. This is also where I found this issue though, annextimelog treats a non-empty stderr from git-annex as something to warn about.
